• Many years of hard work• BAC based approaches towards WGS• Amplification in bacterial culture• More than 20,000 BAC clones• Each containing about 100kb fragment• Together provided a tiling path through each human chromosome• Isolation, select pieces about 2‐3 kb• Subcloned into plasmid vectors, amplification, isolation• recreate contigs• Refinement, gap closure, sequence quality improvement• (less 1 error/ 40,000 bases)

‘Sanger sequencing’ has been the only DNA sequencing method for 30 years but……hunger for even greater sequencing throughputand more economical sequencing technology…

NGS has the ability to process millions of sequencereads in parallel rather than 96 at a time (1/6 of

the cost)Objections: fidelity, read length, infrastructure

cost, handle large volumn of data

• Roche/454 FLX: 2004• Illumina Solexa Genome Analyzer: 2006• Applied Biosystems SOLiDTM System: 2007• Helicos HeliscopeTM : 2010• Pacific Biosciencies SMRT: launching 2010

454 vs Solexa• Homopolymers (AAAAA..)• Read length: 400 bp• Number of reads: 400.000• Per‐base cost greater• Novo assembly, metagenomics• Read length: 40 bp• Number of reads: millions• Per‐base cost cheaper• Ideal for application requiring short reads: ncRNA

• Ancient DNA• DNA mixtures from diverse ecosystems, metagenomics• Resequencing previously published reference strains• Identification of all mutations in an organism• Errors in published literature• Expand the number of available genomes• Comparative studies• Deciphering cell’s transcripts at sequence levelwithout knowledge of the genome sequence

• Sequencing extremely large genomes, crop plants• Detection of cancer specific alleles avoiding traditional cloning• Chip‐seq: interactions protein‐DNA• Epigenomics• Detecting ncRNA• Genetic human variation : SNP, CNV (diseases)

• Key part in regulating gene expression

• Chip: technique to study DNA‐protein interaccions

• Recently genome‐wide ChIP‐based studies of DNA‐protein interactions

• Readout of ChIP‐derived DNA sequences onto NGS platforms

• Insights into transcription factor/histone binding sites in the human genome

• Enhance our understanding of the gene expression in the context of specific environmental stimuli

• Degraded state of the sample mitDNA sequencing• Nuclear genomes of ancient remains: cave bear, mommoth, Neanderthal (106 bp )

Problems: contamination modern humans and coisolation bacterial DNA

De novo genomes

• ncRNA presence in genome difficult to predict by computational methods with high certainty because the evolutionary diversity

• Detecting expression level changes that correlate with changes in environmental factors, with disease onset and progression, complex disease set or severity

• Enhance the annotation of sequenced genomes (impact of mutations more interpretable)

• Characterizing the biodiversity found on Earth• The growing number of sequenced genomes enables us to interpret partial

sequences obtained by direct sampling of specific environmental niches.• Examples: ocean, acid mine site, soil, coral reefs, human microbiome which may

vary according to the health status of the individual

Metagenomics2

microbiome( biological diversity )

• Enable of genome‐wide patterns of methylation and how this patterns change through the course of an organism’s development.

• Enhanced potential to combine the results of different experiments, correlative analyses of genome‐wide methylation, histone binding patterns and gene expression, for example.

• Epigenetics: beyond the sequence. "The major problem, I think, is chromatin. What determines whether a given piece of DNA along the chromosome is functioning, since it's covered with the histones? What is happening at the level of methylation and

epigenetics? You can inherit something beyond the DNA sequence. That's where the real excitement of genetics is now." (James D. Watson). Chromatin is defined as the

dynamic complex of DNA and histone proteins that makes up chromosomes.

• Epigenetics is defined as the chemical modification of DNA that affects gene expression but does not involve changes to the underlying DNA sequence. As the emphasis in

biology is switching away from genetic sequence and towards the mechanisms by which gene activity is controlled, epigenetics is becoming increasingly popular.

Epigenetic processes are essential for packaging and interpreting the genome, are fundamental to normal development and are increasingly recognized as being involved

in human disease. Epigenetic mechanisms include, among other things, histonemodification, positioning of histone variants, nucleosome remodelling, DNA

methylation, small and non‐coding RNAs. (Nature, 7 Aug 2008).

After HumanGenome Project

Basic tools exist tocharacterize the biologybehind human diseases

• Common variants have not yet completly explained complex disease genetics rare alleles also contribute

• Also structural variants, large and small insertions and deletions

• Accelerating biomedical research

• Extreme example: multiplexing the amplification of 10 000 human exons using primers from a programmable microarray and sequencing them using NGS.

Bridging common and rare disease• Common to rare• Splitting up of fields in rarer subclasses• More homogeneous subgroups:

• Smaller, cheaper, shorter trials• Longer cost recovery period under patent

• Large biobanks needed for recruitment of small subgroups • Rare to common• Good human models for therapy development: • one knows what one should see when it works ‐ extended use later • Therapy business models more viable than thought• Next gen sequencing causes rapid advances, new therapies• Large, well‐informed and organized patient constituency
